摘要：
A circuit within an implantable cardiac stimulation device monitors impedance of an electrode configuration including first and second electrodes in electrical contact with a heart. The circuit is within the implantable cardiac stimulation device which applies stimulation pulses having a current and a voltage magnitude across the electrode configuration. The circuit that monitors impedance of an electrode configuration provides an impedance digital output proportional to the ratio of a stimulation pulse voltage and current.
